Abstract

A lithium secondary battery of flat type comprises a positive electrode (1) that includes a positive-electrode mixture (11) covered integrally with an electrolyte layer (13) consisting only of an electrolyte identical with the electrolyte contained in the positive-electrode mixture (11), and a negative electrode (2) that includes a negative-electrode mixture (21) covered integrally with an electrolyte layer consisting only of an electrolyte identical with the electrolyte contained in the negative-electrode mixture (21). The positive electrode (1) and the negative electrode (2) are opposed with the electrolyte layers (13 and 23) interleaved.
